Recall Sweep Trace – Control Byte #33 (21h)
NOTE: This command is new to the S33xD. Use it instead of Control Byte #17 to access new features.
Description: Queries the Site Master for sweep trace data.
NOTE: Before you can recall a sweep stored in non-volatile memory (trace numbers 1-200) you must
build a trace table in the Site Master’s RAM. Use Control Byte #24 to build the trace table. Since the
trace table exists in RAM, Control Byte #24 must be executed every time the Site Master’s power is cy-
cled.
Bytes to Follow: 1 byte
0 = Last sweep trace before entering remote mode (sweep trace in RAM)
1- 200 = Specific saved sweep number (stored sweeps in Flash memory)
Site Master Returns:
1-2) # of following bytes (total length - 2)
